nedenini bulamıyorum Ben android bir form üzerinde çalışıyorum bir damla açılan değerlerin üstüne yerleştirilen başka bir açılır menü değeri seçerek bir açılan değerleri render. Bu yüzden, Üniversite açılır listesinden bir Üniversite seçiyorum ve seçtiğim kurumların değerlerini veriyorum ve kurumlara açılan listeye eklediğimde, Kurum açılır listesinden bir Kurum seçiyorum. Buraya kadar her şey iyi ama bundan sonra tekrar üniversiteyi değiştirirsem, uygulama çöküyor. Sorun, Logcat'ta NullPointerException gösteriyor, ancak çökmekte olduğu satır sayısını veya kilitlenme nedenini göstermiyor.Android: NullPointerException
Logcat: Eğer adaptör null set çünkü

Çalıştığını kontrol edeyim. – Shivam
Bu satırın yerine ne koyabileceğimi söyler misin? – Shivam
spinner.setEnabled (null) yerine spinner.setEnabled (false) kullanın, bu hiçbir şey spinnerdan seçilemez. –
